the gulf stream is a major ocean current. Where does the current travel, and how does it affect climate conditions in Europe?
Sergio [31]

Answer:

The Gulf Stream is an intense, warm ocean current in the western North Atlantic Ocean.

Since the Gulf Stream also extends toward Europe, it warms western European countries as well. In fact, England is about the same distance from the equator as cold regions of Canada, yet England enjoys a much warmer climate. If it weren't for the warm water of the Gulf Stream, England would have a much colder climate.

-Dominant- [34]

Answer:

Hi,

Geologists obtain indirect evidence about the earth’s interior by studying seismic waves produced.

Explanation:

Geologists are able to study the layers of the interior of the earth by observing the seismic waves patterns. The recorded data for the waves can show how the waves traveled through the earth and the path followed which will reveal the structure of the interior of the earth. The speed and magnitude of the wave can further reveal the characteristics of the earth’s interior.

Best wishes!
